what is Geothermal Energy
energy is transferred from one body to the other due to different temperatures
what is heat
the heat required to raise the temperature of the unit mass of a given substance by a given amount
what is a specific heat capacity
the scale of temperature in which absolute zero is watched
what is the Kelvin Scale
